This report presents statistics on U.S. exports from and
imports into the U.S. Customs territory (includes the 50
States, the District of Columbia, and Puerto Rico) by air.
The data have been compiled primarily from export
declarations and import entries during the regular processing
of statistics on foreign trade shipments. Effective January
1975, this report presents data for all individual ports (and
Customs districts) through which air shipments were made.
Prior to January 1975 data were shown only for those
Customs districts having combined exports and imports by
air valued at $1.5 million or more during the preceding
calendar year. A complete list of districts and ports is
presented in Schedule D, Classification of U.S. Customs
Districts and Ports for U.S. Foreign Trade Statistics,
January 1, 1974 edition, as amended.

Exports

These statistics represent exports of domestic and foreign
merchandise combined and include government and non-
government shipments of merchandise by air from the
United States to foreign countries. The statistics, therefore,
include Department of Defense Military Assistance
Program Grant-Aid shipments, shipments for economic
assistance under the Foreign Assistance Act, and shipments
of agricultural commodities under P.L. 480 (The Agricul-
tural Trade Development and Assistance Act of 1954, as
amended) and related laws. Shipments to U.S. Armed
Forces and diplomatic missions abroad for their own use are
not included in the export statistics. U.S. trade with Puerto
Rico and U.S. possessions and trade between U.S. posses-
sions are not included in this report, but exports from
Puerto Rico to foreign countries are included. Merchandise
shipped through the United States in transit from one
foreign country to another, when documented as such with
U.S. Customs, is excluded. The statistics in this report also
exclude shipments by mail and parcel post and exports of
aircraft flown out of the country under their own power, as

well as certain types of transactions not considered to be of
statistical significance, such as personal and household
effects.
The value reported in the export statistics generally is
equivalent to the f.a.s. (free alongside ship) value at the U.S.
port of export, based on the transaction price, including
inland freight, insurance, and other charges incurred in
placing the merchandise alongside the carrier at the U.S.
port of exportation. For exports by air, the port of lading
shown in this report is the port where the merchandise is
loaded on the aircraft which takes the goods out of the
country.
For security reasons, certain commodities are designated
as Special Category commodities, for which security regula-
tions place restrictions upon the type of export information
that may be released. The data shown in this report for
individual Customs ports, districts and continents exclude
exports of Special Category commodities, but overall
shipping weight and value totals for Special Category
commodities are shown. A list of Special Category commod-
ities may be obtained from the Bureau of the Census.
Effective January 1975, the statistics for countries other
than Canada reflect fully compiled data for shipments
valued $1,000 and over combined with estimated data for
shipments valued from $251-$999, based on a 50-percent
sample of such shipments. Prior to January 1975, estimated
data for countries other than Canada were based on a
50-percent sample of shipments valued $251-$499 while
data for shipments valued S500 and over were fully
compiled. For Canada, the statistics continue to reflect fully
compiled data for shipments valued $2,000 and over
combined with estimated data for shipments valued from
$251-S1,999, based on a 10-percent sample of such ship-
ments. Shipping weight and value data for major aggregates
are also estimated for shipments valued under $251. These
estimates are not included in the data shown for individual
Customs ports and districts.

Since the export figures shown include estimates based
on a sample of low-valued shipments, they are subject to
some degree of sampling variability. The table below
provides a rough guide to the general level of sampling
variability of value totals, on a 2 chances out of 3 basis.
Usually the higher value figures will have the lower percent
sampling errors.

Value totals for
"Total" and "North
America" of:

$1,000,000 and over

$500,000-$1,000,000

Imports

These statistics represent general imports, which are a
combination of imports for immediate consumption and
entries into bonded warehouses. The statistics include
government as well as nongovernment shipments of mer-
chandise by air from foreign countries to the United States.
However, American goods returned by the U.S. Armed
Forces for their own use are excluded. VS.S. trade with
Puerto Rico and with U.S. possessions and trade between
U.S. possessions are not included in this report, but imports
into Puerto Rico from foreign countries are included.
Merchandise shipped through the United States in transit
from one foreign country to another, when documented as
such with U.S. Customs, is not reported as imports and is
excluded from the data. Imports by mail and parcel post
and imports of aircraft flown into the United States under
their own power are also excluded from this report as well
as certain transactions not considered to be of statistical
significance, such as personal and household effects.

The Customs value shown in this report represents the
value of imports as appraised by the U.S. Customs Service in
accordance with the legal requirements of Sections 402 and
402a of the Tariff Act of 1930, as amended. It may be
based on the foreign market value, export value, construct-
ed value, American selling price, etc. It generally represents
a value in the foreign country, and therefore excludes U.S.
import duties, freight, insurance, and other charges incurred
in bringing the merchandise to the United States. This
valuation is primarily used for collection of import duties
and frequently does not reflect the actual transaction value.

For imports by air, the port of unlading shown in this
report is the port where the merchandise is unloaded from
the aircraft which brings the goods to the United States.
The statistics shown for individual Customs ports and
districts represent fully compiled data for shipments valued
$251 and over. Data for shipments valued under $251,
reported on formal and informal entries (informal entries
generally contain items valued under $251), are estimated
from a 1-percent sample following standard practice. Sepa-
rate shipping weight and value estimates for shipments
valued under $251 are shown. The shipping weight data are
estimated from the values on the basis of constants that
have been derived from an observation of the value-weight
relationships in past periods.

Since the statistics showing total
carriers include sample estimates
sampling variability. In general, the
have the lower percent sampling
$500,000 and over will generally ha
of less than 3 percent; value totals
generally have a sampling variability

value of imports by all
, they are subject to
higher value figures will
errors. Value totals of
ve a sampling variability
of under $500,000 will
of less than $50,000.

Shipping Weight

Sources of Error in the Statistics

Shipping weight figures, shown for both imports and
exports, represent the gross weight of shipments, including
the weight of moisture content, wrappings, crates, boxes,
and containers (other than containers such as cargo vans and
similar substantial outer containers used for containerized
cargo).

The sampling variability applicable to the dollar figures
will provide an approximate guide to the reliability of the
matching shipping weight figures. For technical reasons, the
sampling variability of the shipping weight will be somewhat
more than for the dollar value figures.

Monthly import and export figures are subject to the
possibility of errors which may arise from various sources.
Among these are errors in the reporting and/or processing of
information as to value, shipping weight and other statistical
factors, month of inclusion, and errors which may result
from the sampling of certain import and export shipments,
discussed above. In the case of imports the information as
to value (and commodity classification, country of origin,
and net quantity) is verified by Customs officials on entries
filed for transactions valued over $250 which are ordinarily
subject to examination for Customs appraisement purposes,
thus considerably reducing the possibility of error. In
addition, the procedures used to compile both the import
and export statistics include clerical and computer process-
ing checks designed to protect the accuracy of the statistics
to the fullest practicable extent.
